The Wave is a program of major transport infrastructure projects proposed for the Sunshine Coast, announced as part of the Brisbane 2032 Olympic and Paralympic Games Delivery Plan. The program is proposed to be delivered in three stages, with Stages 1 and 2 delivering a heavy passenger rail line from Beerwah to Birtinya (formerly the Direct Sunshine Coast Rail Project), integrating with Stage 3, which proposes a metro‑style service extending to the Sunshine Coast Airport.

The Wave Stage 2 would extend rail services from Caloundra to Birtinya, including two new stations at Aroona and Birtinya. The project aims to increase public transport use, support a shift from private vehicles to public transport, reduce road congestion, and contribute to a more sustainable and efficient transport network for the region.
